From: Critical scaling of icosahedral medium-range order in CuZr metallic glass-forming liquids

The scaled size distribution follows an excellent scaling behaviour with the scaled cluster size ST.
Here S is the cluster size. Tc is the critical point. τ and σ are scaling critical exponents. It can be seen that all the cluster number densities fall onto the same curve representing the graph of scaling function f(S/Sc).
